             in which L, R 1 , R 3  and A are as defined in the disclosure, to a plurality of processes for preparing these compounds and their use for controlling unwanted microorganisms, and to novel intermediates and their preparation.

The present patent application has been filed under 35 U.S.C. 371 as a national stage application of PCT/EP2004/011397, filed Oct. 12, 2004, which was published in German as International Patent Publication WO 2005/042493 on May 12, 2005, and is entitled to the right of priority of German Patent Applications 10349499.5, filed Oct. 23, 2003, and 10352082.1, filed Nov. 7, 2003.

The present invention relates to novel hexylcarboxanilides, to a plurality of processes for their preparation and to their use for controlling unwanted microorganisms.

It is already known that numerous carboxanilides have fungicidal properties (cf., for example, WO 03/010149, WO 02/059086, WO 02/38542, WO 00/09482, EP-A0 591 699, EP-A 0 589 301 and EP-A 0 545 099). Thus, for example, 5-fluoro-1,3-dimethyl-N-[2-(1,3,3-trimethylbutyl)phenyl]-1H-pyrazole-4-carboxamide is known from WO 03/010149, N-allyl-N-[2-(1,3-dimethylbutyl)phenyl]-1-methyl-3-(trifluoromethyl)-1H-pyrazole-4-carboxamide is known from WO 02/059086 and N-[2-(1,3-dimethylbutyl)phenyl]-1-methyl-4-(trifluoromethyl)-1H-pyrrole-3-carboxamide is known from WO 02/38542. The activity of these compounds is good; however, at low application rates it is sometimes unsatisfactory.

This invention now provides novel hexylcarboxanilides of the formula (I)

If appropriate, they can also be used as intermediates or precursors in the synthesis of other active compounds.

According to the invention, it is possible to treat all plants and parts of plants. Plants are to be understood here as meaning all plants and plant populations, such as desired and undesired wild plants or crop plants (including naturally occurring crop plants). Crop plants can be plants which can be obtained by conventional breeding and optimization methods or by biotechnological and genetic engineering methods or combinations of these methods, including the transgenic plants and including plant cultivars which can or cannot be protected by plant breeders' certificates. Parts of plants are to be understood as meaning all above-ground and below-ground parts and organs of plants, such as shoot, leaf, flower and root, examples which may be mentioned being leaves, needles, stems, trunks, flowers, fruit-bodies, fruits and seeds and also roots, tubers and rhizomes.

Suitable solid carriers are: for example ground natural minerals such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals such as finely divided silica, alumina and silicates. Suitable solid carriers for granules are: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, or else synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks.

The formulations generally comprise between 0.1 and 95 percent by weight of active compound, preferably between 0.5 and 90%.

The active compounds according to the invention can, as such or in their formulations, also be used in a mixture with known fungicides, bactericides, acaricides, nematicides or insecticides, to broaden, for example, the activity spectrum or to prevent development of resistance.

WO-96/37494, WO-98/25923), and preparations which comprise insecticidally active plant extracts, nematodes, fungi or viruses.

A mixture with other known active compounds, such as herbicides, or with fertilizers and growth regulators, safeners and/or semiochemicals is also possible.

In addition, the compounds of the formula (I) according to the invention also have very good antimycotic activity. They have a very broad antimycotic activity spectrum in particular against dermatophytes and yeasts, moulds and diphasic fungi (for example against Candida species such as Candida albicans, Candida glabrata) and Epidermophyton floccosum, Aspergillus species such as Aspergillus niger and Aspergillus fumigatus, Trichophyton species such as Trichophyton mentagrophytes, Microsporon species such as Microsporon canis and audouinii. The list of these fungi does by no means limit the mycotic spectrum which can be covered, but is only for illustration.

The active compounds can be used as such, in the form of their formulations or the use forms prepared therefrom, such as ready-to-use solutions, suspensions, wettable powders, pastes, soluble powders, dusts and granules. Application is carried out in a customary manner, for example by watering, spraying, atomizing, broadcasting, dusting, foaming, spreading, etc. It is furthermore possible to apply the active compounds by the ultra-low volume method, or to inject the active compound preparation or the active compound itself into the soil. It is also possible to treat the seeds of the plants.

When using the active compounds according to the invention as fungicides, the application rates can be varied within a relatively wide range, depending on the kind of application. For the treatment of parts of plants, the active compound application rates are generally between 0.1 and 10000 g/ha, preferably between 10 and 1000 g/ha. For seed dressing, the active compound application rates are generally between 0.001 and 50 g per kilogram of seed, preferably between 0.01 and 10 g per kilogram of seed. For the treatment of the soil, the active compound application rates are generally between 0.1 and 10000 g/ha, preferably between 1 and 5000 g/ha.

As already mentioned above, it is possible to treat all plants and their parts according to the invention. In a preferred embodiment, wild plant species and plant cultivars, or those obtained by conventional biological breeding, such as crossing or protoplast fusion, and parts thereof, are treated. In a further preferred embodiment, transgenic plants and plant cultivars obtained by genetic engineering, if appropriate in combination with conventional methods (Genetically Modified Organisms), and parts thereof, are treated. The term “parts” or “parts of plants” or “plant parts” has been explained above.

Particularly preferably, plants of the plant cultivars which are in each case commercially available or in use are treated according to the invention. Plant cultivars are to be understood as meaning plants having new properties (“traits”) and which have been obtained by conventional breeding, by mutagenesis or by recombinant DNA techniques. They can be cultivars, varieties, bio- or genotypes.

Depending on the plant species or plant cultivars, their location and growth conditions (soils, climate, vegetation period, diet), the treatment according to the invention may also result in superadditive (“synergistic”) effects. Thus, for example, reduced application rates and/or a widening of the activity spectrum and/or an increase in the activity of the substances and compositions which can be used according to the invention, better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to water or soil salt content, increased flowering performance, easier harvesting, accelerated maturation, higher harvest yields, better quality and/or a higher nutritional value of the harvested products, better storage stability and/or processability of the harvested products are possible which exceed the effects which were actually to be expected.

The transgenic plants or plant cultivars (i.e. those obtained by genetic engineering) which are preferably to be treated according to the invention include all plants which, in the genetic modification, received genetic material which imparted particularly advantageous useful properties (“traits”) to these plants. Examples of such properties are better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to water or soil salt content, increased flowering performance, easier harvesting, accelerated maturation, higher harvest yields, better quality and/or a higher nutritional value of the harvested products, better storage stability and/or processability of the harvested products. Further and particularly emphasized examples of such properties are a better defence of the plants against animal and microbial pests, such as against insects, mites, phytopathogenic fungi, bacteria and/or viruses, and also increased tolerance of the plants to certain herbicidally active compounds. Examples of transgenic plants which may be mentioned are the important crop plants, such as cereals (wheat, rice), maize, soya beans, potatoes, cotton, tobacco, oilseed rape and also fruit plants (with the fruits apples, pears, citrus fruits and grapes), and particular emphasis is given to maize, soya beans, potatoes, cotton, tobacco and oilseed rape. Traits that are emphasized are in particular increased defence of the plants against insects, arachnids, nematodes and slugs and snails by toxins formed in the plants, in particular those formed in the plants by the genetic material from Bacillus thuringiensis (for example by the genes CryIA(a), CryIA(b), CryIA(c), CryIIA, CryIIIA, CryIIIB2, Cry9c, Cry2Ab, Cry3Bb and CryIF and also combinations thereof) (hereinbelow referred to as “Bt plants”). Traits that are also particularly emphasized are the increased defence of the plants against fungi, bacteria and viruses by systemic acquired resistance (SAR), systemin, phytoalexins, elicitors and resistance genes and correspondingly expressed proteins and toxins. Traits that are furthermore particularly emphasized are the increased tolerance of the plants to certain herbicidally active compounds, for example imidazolinones, sulphonylureas, glyphosate or phosphinotricin (for example the “PAT” gene). The genes which impart the desired traits in question can also be present in combination with one another in the transgenic plants. Examples of “Bt plants” which may be mentioned are maize varieties, cotton varieties, soya bean varieties and potato varieties which are sold under the trade names YIELD GARD® (for example maize, cotton, soya beans), KnockOut® (for example maize), StarLink® (for example maize), Bollgard® (cotton), Nucoton® (cotton) and NewLeaf® (potato). Examples of herbicide-tolerant plants which may be mentioned are maize varieties, cotton varieties and soya bean varieties which are sold under the trade names Roundup Ready® (tolerance to glyphosate, for example maize, cotton, soya bean), Liberty Link® (tolerance to phosphinotricin, for example oilseed rape), IMI® (tolerance to imidazolinones) and STS® (tolerance to sulphonylureas, for example maize). Herbicide-resistant plants (plants bred in a conventional manner for herbicide tolerance) which may be mentioned also include the varieties sold under the name Clearfield® (for example maize). Of course, these statements also apply to plant cultivars which have these genetic traits or genetic traits still to be developed, and which will be developed and/or marketed in the future.

The plants listed can be treated according to the invention in a particularly advantageous manner with the compounds of the general formula (I) or the active compound mixtures according to the invention. The preferred ranges stated above for the active compounds or mixtures also apply to the treatment of these plants. Particular emphasis is given to the treatment of plants with the compounds or mixtures specifically mentioned in the present text.

The preparation and the use of the active compounds according to the invention is illustrated by the examples below.

Preparation of Starting Materials of the Formula (II) Example (II-1)

300.0 mg (1.9 mmol) of 3-formyl-1-methyl-1H-pyrazole-4-carboxylic acid are dissolved in 60 ml of dichloromethane, and 1.0 g (4.9 mmol) of phosphorus pentachloride is added. After 1.5 h at room temperature, the mixture is poured onto ice-water and extracted with dichloromethane, and the extracts are dried over magnesium sulphate, filtered and concentrated under reduced pressure.

This gives 384.0 mg (86% of theory) of 3-dichloromethyl-1-methyl-1H-pyrazole-4-carbonyl chloride [logP (pH 2.3)=1.80].

Preparation of Starting Materials of the Formula (VII) Example (VII-1)

16.0 ml (170 mol) of acetic anhydride are added to a solution comprising 10.0 g (57 mmol) of methyl 4,4-dimethoxy-3-oxobutyrate in 9.0 g (85 mmol) of trimethyl orthoformate. The reaction mixture is heated under reflux for 16 h.

Distillation of the reaction mixture (boiling point 132-135° C., 0.2 bar) gives 7.0 g (56% of theory) of methyl 4,4-dimethoxy-2-methoxymethylene-3-oxobutyrate.

Preparation of Starting Materials of the Formula (IX) Example (IX-1)

At −5° C., a solution comprising 2.0 ml (38 mmol) of methylhydrazine in 340 ml of methanol is slowly added dropwise to 7.5 g of methyl 4,4-dimethoxy-2-methoxymethylene-3-oxobutyrate. After the addition has ended, the reaction mixture is stirred at room temperature for 16 h and concentrated under reduced pressure.

Column chromatography (mobile phase gradient cyclohexane/ethyl acetate) gives 6.5 g (77% of theory) of methyl 3-dimethoxymethyl-1-methyl-1H-pyrazole-4-carboxylate.

Preparation of Starting Materials of the Formula (X) Example (X-1)

10 ml of concentrated hydrochloric acid is added to a solution of 2.1 g (10 mmol) of methyl 3-dimethoxymethyl-1-methyl-1H-pyrazole-4-carboxylate in 20 ml of dioxane, and the mixture is stirred at room temperature for 1.6 h. For work-up, the mixture is concentrated under reduced pressure and the residue is taken up in 200 ml of methylene chloride and washed with 50 ml of water. The organic phase is dried over magnesium sulphate, filtered and concentrated.

This gives 1.6 g (94% of theory) of methyl 3-formyl-1-methyl-1H-pyrazole-4-carboxylate [logP (pH 2.3)=0.46].

Preparation of Starting Materials of the Formula (XI) Example (XI-1)

6.0 g (35.68 mmol) of methyl 3-formyl-1-methyl-1H-pyrazole-4-carboxylate are dissolved in 180 ml of tetrahydrofuran and 90 ml of water, and 0.94 g (39.25 mmol) of lithium hydroxide is added. The reaction mixture is stirred at room temperature for 16 h, the organic solvent is removed under reduced pressure and the aqueous phase that remains is acidified with dilute hydrochloric acid and extracted three times with in each case 100 ml of ethyl acetate. The organic phases are dried over magnesium sulphate, filtered and concentrated.

This gives 4.28 g (78% of theory) of 3-formyl-1-methyl-1H-pyrazole-4-carboxylic acid of logP (pH=2.3)=−0.19.

Preparation of Starting Materials of the Formula (XII) Example (XII-1)

46.1 mg (0.27 mmol) of methyl 3-formyl-1-methyl-1H-pyrazole-4-carboxylate are dissolved in 10 ml of dichloromethane, and 142.9 mg (0.67 mmol) of phosphorus pentachloride are added. The reaction mixture is stirred at room temperature for 1.5 h, added to water and extracted with diethyl ether, and the extract is dried over magnesium sulphate and concentrated under reduced pressure.

This gives 53.0 mg (86% of theory) of methyl 3-(dichloromethyl)-1-methyl-1H-pyrazole-4-carboxylate of logP (pH 2.3)=1.80.

This methyl ester can be hydrolysed in the customary manner. This gives 3-(dichloromethyl)-1-methyl-1H-pyrazole-4-carboxylic acid which is coupled with compounds of the formula (III) either directly or after conversion into the acid chloride.

The determination of the logP values given in the preparation examples and tables above is carried out in accordance with EEC Directive 79/831 Annex V.A8 by HPLC (High Performance Liquid Chromatography) on a reversed-phase column (C 18). Temperature: 43° C.

The determination is carried out in the acidic range at pH 2.3 using the mobile phases, 0.1% aqueous phosphoric acid and acetonitrile; linear gradient from 10% acetonitrile to 90% acetonitrile.

Calibration is carried out using unbranched alkan-2-ones (of 3 to 16 carbon atoms) with known logP values (determination of the logP values by the retention times using linear interpolation between two successive alkanones).

The lambda max values were determined in the maxima of the chromatographic signals using the UV spectra from 200 nm to 400 nm.
